Missing new line in text when export to PDF (Read 4195 times)

	Hi. I have a DiagramLite application that is used to draw some shapes and links. I want to export this to PDF, so I can print them later. If I have a shape with text in it, e.g "This i a test for carriage return and blanks" It comes out in the PDF document like this "This i a test for carriage return and blanks" Somewhere my blank lines are removed. When I debug and make override of the Draw method, the text looks OK. The XML also looks OK. Any ideas?? Regards Anders

	Hi, It seems our PdfGraphics.DrawString method skips empty lines. You might try to set the EnableStyledText property on the shapes before exporting - this should call DrawString for each line separately on the correct positions. I hope that helps, Stoyan

	Hi again. I tried what you proposed, but with the same result. Both for user-defined shapes and standard shapes. Any more ideas? Regards, Anders

	It worked in my test, node #2 here has a few blank lines: http://mindfusion.eu/_temp/styledtext.pdf Are you sure you have set EnabledStyledText for each individual node? Setting Diagram.EnabledStyledText won't affect existing nodes but only new ones. Stoyan

	Ahhhh My mistake. I thought that it would be enough by setting the property for the diagram and then loading with LoadFromString(str). I now have set the property for each node, and it works fine. Many thanks. Regards Anders

	Hi again. Guess I was to quick. I have a custom node, I don't get it to work with blanks for this one. I have a override of the draw method. It looks like this. What am I missing? Regards Anders Code public override void Draw(MindFusion.Drawing.IGraphics graphics, MindFusion.Diagramming.RenderOptions options) { this.EnableStyledText = true; //Get textarea for myText SizeF textSize = graphics.MeasureString(myText, Font, (int)Bounds.Width, TextFormat); RectangleF myTextBounds = RectangleF.FromLTRB( Bounds.X, Bounds.Y, Bounds.Right, textSize.Height); //Draw the text graphics.DrawString(myText, Font, System.Drawing.Brushes.Black, myTextBounds, TextFormat); }

	Hi, Call Diagram.DrawStyledText() to draw it as EnableStyledText does for ShapeNodes. I hope that helps, Stoyan
